Witness WILLIAM PRICE. OF CINCINNATI, OHIO.

Letters Patent N .'96,4 81, dated November 2, 1869 IMPROVED DUMPING-CARFOR GRADING.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it knowuthat I, WILLIAM PRICE, ofCincinnati, in the county of Hamilton, and State of Ohio, have inventedcertain new and useful Improvements in Dumping-Oars for Grading, and thefollowing is a. full, clear, and exact description of the same,reference being bad to theaccompanyingdrawings, making a part of thisspecification, in Which Figure 1 represents an end view. of thecar-truck and body, the elevated supporting-fi'ames and camtruunions ordumping-device 0n the track, in position for loading and carrying earth,860.

Figure 2 shows an end view of the same, with the car-body tipped up onone side, in position for dump- .ing or discharging its contents.

Figure 3 shows the inside of the plate of the camtrunnions, with theflange. and ribs for securing it firmly 'to the end of the car-body.

Figure 4 shows an edge view of the same, as secured to a broken-oftsection ot'thc end ofthe body.

Figure 5 is a section through thesame, showing the bolts and nuts foriasteningit on.

Figure 6' shows a side elevation of the dumping-car, flanged Ytrunnions, supportingframes, truck-wheels, and track complete.

The object of my invention is to furnish increased facilities forremoving earth, in grading roads, streets, or for street orotherrailroad-tracks, or for excavating for canal, mill-races, or otherpurposes; and

It consists First, in a single car-body -0r earth-receiver, soconstructed that no gates or side openings are required in it, todischarge the load or contents on either side of the truck, at thepleasure ot' the operator.

Second, in the arrangement-torhalwing and balancing the car-body oncam-journals or irregular-shaped trhnnions, secured on the outside ofthe ends.

'lhirdly, in the construction oi" the trunuious or dmnping-derice, andtheir supporling-frames, so thatthe car-body will resume its positioncentrally on the truck, for loading and transporting, and will admit ofbeing tipped up and over, on either side, suflicicntly to discharge thecontents'by a man or boy.

To enable others to make and use my improvements in dlunpiug-cars, Iar'ill describe them more fully, re-' ferring to the drawings, and theletters marked there- The truck-frame A may be be made of hard -woodjoist or plank, and secured together by bolt-rods a a, extending throughboth the-side pieces, they being so placed, in relation to the cross orend-pieces of the truck-trams, as to support the elevated frames B B, onwhich the body'O hangs.

The car-body or earth-receiver Oma-y be made of hard wood; theframe-timbers b 1) maybe light, and of small dimensions; and the box orlining a may be of thin plank or boards, and be sufiiciently strong anddurable for the purpose, as it can all be secured at the corners, andall of the .joints in the firmcstmanner, there being no slides or doorsto be opened, to discharge the contents, which, when used in theordinary method of constructing dirt or coal-o ars,'very much weaken thebody, and strain the joints, and wear out the slides.

The dumping-device or cam-trunnions D D are made of metal, with aprojecting 'flange, d, aml are provided with, ribs 0 e, to fit on to thecleats ff on the ends of the car-body O, and are secured by bolts nearlycentrabthe l'urder portion being so shaped that it finds the centre ofthe suppurting-li'mnes B B, and rests securely on a level when the caris empty, but when filled full, the larger portion of the contents beingabove the line of its bearings, it isvcry easily lifted fromeither sideby taking hold of one of the handles g, secured to the bottom for thatpurpose.

The side-pieces ot the truck-flame A are also provided with stirrupshit, to put one foot in, so as to enable a boy or a man of low statureto easily liftthe side ofthe car until it preponderates and dumps itsload.

The supporting-flames B Bare so shaped on the top, as to conform to thecam-trunnions 1) 1), and form a stop on both sides, to prevent the bodyfrom being cast off in dumpin The advantages of my improved dumping-carare that they can be made much lighter in proportion to their capacityfor. carrying a load, and are more durable,

there being no doors or hinges or slides to get disarranged orbroken,.and are operated, in discharging a load, in less time, andwithgreater case, than any that have ever before come to mynotice. 5

\Vhat I claim as lily-invention, is p 1. A single car-body, dumping oneither side of the truckwhich supports it, as herein described.

2. Placing the supporting and dumping-device on the outside ends ofthecar-body, as and for the purpose herein-specificd.

3. Thecam-trunnions D D as constructed, in com bination with thesupporting-flames B B, car-body O, and truck A, all arranged to'operatesubstantially as herein set forth; p

In testimonyv whereof, I hereunto subscribe my name, in the'presence ofiWILLIAM PRICE. Witnesses:
